Abstract: 1,165,039. Grinding. WESTINGHOUSE ELECTRIC CORPORATION. 7 Nov., 1967 [16 Nov., 1966], No. 50493/67. Heading B3D. [Also in Division G1] A carriage 18 traversing a grinding wheel 16 along a roll 10 to be ground is driven along a track 20 by a rack and pinion 24, 22, and has its position measured by a potentiometer 40 geared at 47 to the pinion-driving motor 26, the wiper 44 potential being compared in respective circuits RA, RB, RC, RD with preset potentials from potentiometers 54, 60, 66, 72 to control the slowdown and reversal of the carriage movement. The actual carriage position is indicated by a voltmeter V. The circuits RA, RB, RC and RD are similar, the circuitry of RD being shown in full as comprising two switching transistors E1, E2, which actuate a relay WD only when input XD becomes negative with respect to input YD. Potentiometers 60, 66 define the positions LS, RS on the track 20 at which relays WB, WC operate to connect resistors 110, 112 into the voltage supply circuit 32 to slow the motor 26, one set of contacts RB1, RC1 associated with each of the relays WB, WC, being connected across these resistors for this purpose. The relays WA, WD which define the limits of carriage movement, L, R, have two sets of contacts RA1, RA2, RD1, RD2, which are connected into the operating circuit (lower left portion of Figure) of two further relays CL, CR. These relays have certain contacts CL3, CL4, CR3, CR4 connected in the motor drive circuit 32 to effect reversal of motion, so that a reciprocatory movement is obtained for the carriage 18. The relays may be arranged to control braking, processing, and other functions, as well as the slowing and reversing described.

Filed: 1972-11-08
Abstract: 1397341 Boots &c SHOE & ALLIED TRADES RESEARCH ASSOCIATION 5 Nov 1973 [8 Nov 1972] 51590/72 Heading A3B. A method of treating a lasted shoe upper to improve the shape retention of the upper after the last has been slipped includes the stages of first subjecting the lasted upper to a dry heat treatment at an elevated temperature and subsequently subjecting the lasted upper to a steam treatment in a saturated atmosphere at a temperature not less than 85‹C, the lasted upper being partially cooled between the two treatments. The dry heat treatment may include treatment in hot circulating air and/or a radiant heat treatment. The elevated temperature of the dry heat treatment is within the range 100‹ to 180‹C, preferably in the range 110‹ to 130‹C for leather uppers and in the range 140‹ to 180‹C for poromeric uppers. The duration of the dry heat treatment is such that the upper attains a temperature higher than that prevailing in the steam treatment zone, e.g. about 3 minutes. The cooling may be carried out by subjecting the upper to a blast of cold air or to ambient air, and the duration is such as to cool the upper not more than 20‹ below the temperature of the steam treatment, e.g. about 21 seconds. The steam treatment is conducted at a temperature of above 85‹C, preferably 90‹ to 95‹C, for about 1 minute. The method may be carried out using apparatus consisting of a conveyor which conveys the uppers through tunnels defining the treatment zones. Alternatively the apparatus described in Specification 1039296 may be modified to carry out the method.

The sheet is manufactured by pressing an arrangement of cold projection, e.g. needles, against a heated sheet. In moving towards the sheet the needles can follow curved, slanting or different paths. The sheet can be formed by passing a heated sheet between two endless belts carrying cold projections, Fig. 6, not shown. In other embodiments the hollow projections are formed by projecting ballbearings or pulses of cold fluid on to a heated sheet. The tips of the hollow projections can be removed to form a perforated sheet. The sheets can be used to form laminates by bonding facing sheets to one or both surfaces. Such facing sheets can be, e.g. metal glass, paper, wood, plaster, plastics, plastics coated paper or fabric. The core sheet can be mirrored. When a fabric facing sheet is used this can be subsequently impregnated with a hardenable composition, e.g. a resin. In Figs. 10 and 11, not shown, a composite laminated panel is heated along a narrow strip at one side and then folded. A butt weld can be formed by heating the edges of two sheets and then pressing them together, Fig. 12, not shown.
